Stereo amplifier 3W + 3W using ic BA5406

IC number is BA5406 IC stereo audio amplifier size 3 watt + 3 watt.The circuit is small and easy to create.Suitable for expanding the use of music in a private room.Or may be used in any trial.
When raising the power supply 12 volts to this circuit.Input the left and the right to access the input pin, to pin 5 and pin 8 of IC.The signal through the C1 and C2 are coupling signal.To prevent DC, to interfere in the circuit.Then the amplifier IC is not a return phase.Exit output, Pin 2 and Pin 11.And the output signal out of each channel, left and right through C9 and C10.Add to block DC and low frequency stability.Then went out to the speakers.The C7 and C8 are connected to pins 3 and pin 10 of IC, respectively.The pin 3 and pin 10 is pin Boot Strap will help to gain a better.The C5 and C6 are connected to pins 6 and Pin 7.A pin Filter, the C5 and C6 serve cut noise from the IC.

The multi-purpose Amplifier using TDA2030

This The multi-purpose Amplifier using TDA2030. It is have power 8 watt (RMS) at 8 ohm loudspeakers. It is have low noise be valuable THD (Total harmonic distortion) 0.1% , When friends use Power supply Voltage Source 28 Volt at 4 ohm loudspeakers have output power 12Watt. But be high class the noise increases to are 2 times. Besides still three be usable with Volt supply about 9Volt , but there is the electric power is down respectively. The VR1 use for Volume popularity level of sound signal. By if a friend can’t seek 22K values use 50K values can replace. For other detail about the integrated circuit TDA2030 and other , friends see in the circuit better yes.
